Re: wl127x: Unable to associate with a WPA2-PSK AP

["José Miguel Gonçalves" <jose.goncalves@inov.pt>]

Hi Arik,

Yep, that patch solved the kernel warning, but the association with  the AP is 
still lost after 3 warnings;

wlcore: Beacon loss detected. roles:0xff

To use the driver in the Luca's tree I need to do some work to adapt my platform 
to the latest kernel version, what I would like to avoid  for now.
Is there any set of patches to put  the driver in vanilla kernel 3.9 in a more 
stable condition?

Best regards,
Jose Gonçalves
